ZHANG Jun-yi,SU Wei-ci,ZHANG Jun-yi,SU Wei-ci
Journal of Chongqing Normal University , 2010,
Abstract: Based on conclusion of leading industries of the main characteristics and selection methods to compare the advantages and disadvantages, we use shift-share-method and select 29 manufacturing industry departments at two time points in 2002 and 2007 of Chongqing as analysis objects, with the circumstance of 29 manufacturing industry departments of the whole country for reference, to make a comprehensive comparative analysis of the quota to deviate weight, structure to deviate weight and competition ability to deviate weight of 29 manufacturing industry departments of Chongqing , we use of Shift-Share-Method to 29 manufacturing sectors of the share of component analysis, structural components and competitiveness to deviate from the deviation component analysis of Chongqing and draw Shift-Share analysis diagram. Through the graph analysis we screen out transportation equipment manufacturing, non-ferrous metal smelting and rolling processing industry, electrical machinery and equipment manufacturing industry in three industrial sectors, which are most likely to become the dominant industry, the advantages of industrial sectors. The above three industries, existing infrastructure and future development are analyzed in the Chongqing municipality. "Eleventh Five-Year Plan" to determine the focus of the development of industries to compare the results more consistent, indicating filter out the leading industry more in line with the actual Chongqing. The results of the analysis show that the Shift-Share-Method has a certain degree of objectivity, but also are easy to overlook the smaller lack of new industries. Therefore, to determine the future of the leading industries of Chongqing, itis yet to be fully comprehensive consideration of various influencing factors and careful determined.

Journal of Chongqing Normal University , 2009,
Abstract: Based on the data from 1997 to 2007, this paper tries to make a comprehensive evaluation of 40 districts in Chongqing by using economic location quotient and Kuznets ratio. Since 1997, the city has been subdivided into four economic regions, i.e. developed area with rapid development, sub-developed area with steady growth, moderately developed area with rapid increase, and less-de-veloped area with low levels. The Differences reveal the space characteristics of each district in that the economic differences within ile the differences in the different zones are expanding. The results shows that the interior difference of the developed Metropolis, the economic corridor in West Chongqing and the ecological economic zone of Three Gorges reservoir is narrowing. But the interregional gap of the three areas is expanding rather than narrowing. At last, this paper aims to make further analysis of the main causes for the economic and cultural foundation, the environmental loading capacity and the Government's regional development policy, and put forward some countermeasures.

Abstract: Resolving the two dimensional Fokker Planck equation, evolutions of the driven current and its profile on HT 7 tokamak are obtained. The simulated results are nearly in agreement with the experimental data, which supplies a theoretical guidance for lower hybrid current drive (LHCD) experiments on HT 7 tokamak. In addition, the effect of radial diffusion of fast electrons on the driven current during LHCD is considered by means of solving the current diffusion equation.

Journal of Chongqing Normal University , 2009,
Abstract: By the method of gray correlation degree and loeation quotient this paper calculate the relational degree of department of industrial specialization and economic growth in Chongqing in 1998-2006, and analyse the result of calculation. The results showed that: the industry of transport equipment manufacturing in Chongqing are the most comparative advantage industries , but not the most closely associated with the economic growth the industry;the Water production and supply industry in Chongqing has become the major industry inhibiting the lasting growth of economy. By this analysis, clear the condition of regional comparative advantages in Chongqing and note that as focusing the labor geographical division, not only should the industrial ratio be co-ordinated but also cultivating the potential of leading industries including pharmaceutical manufacturing.
Study of Evaluation Characterisitics of Ecological Infrastructure and Countermeasure in Pivot Cities of Three Gorges Reservoir Region
QIN Qu,FENG Wei-bo,SU Wei-ci,Peng Li
Journal of Chongqing Normal University , 2009,
Abstract: Ecological infrastructure is involved with ecological security and health of cities.At present there are so many studies about it. However, quantitative study is muchindetermination and imperfection. In this paper in order to ravel out this problem, the evaluation indexes system are established on the basis of air system, greenbelt system and water system from the conception and connotation of ecological infrastructure. They do not only consult inside and outside of Chinese ecological cities and garden cities but also consult with internal and international related index standard. Analytic Hierarchy Process (AHP) and the method of comprehensive index evaluation are applied to establish the evaluation model. Then it studies the quality and evolvement characteristics of ecolocal infrastructure in the case of main town of Chongqing, Yichang, Fulin, Wanzhou——the four pivot cities of Three Gorges Reservoir Region from 2002 to 2005. Finally, the paper draws a conclusion by qulitative and quantitative analysis showing that the quality of ecological infrastructure of four cities is in rise. At present, the quality of ecological infrastructure of Yichang and Fulin remains with better grade; Wanzhou and the main town of Chongqin belongs to common grade. The integrated quality conditins of ecological infrstructure of these four cities follow the sequence (from high to low ) : Yichang> Fulin> Wanzhou> main town of Chongqing. The quality of ecological infrastructure of four cities is known through evaluation analysis, which has provided a scientific basis for the cities Three Gorges Reseveoir Region in programming.
Vacuum Rabi Oscillation of an Atom without Rotating-Wave Approximation

WANG Fa-Qiang,LIU Wei-Ci,LIANG Rui-Sheng,

中国物理快报 , 2008,
Abstract: We have investigated vacuum Rabi oscillation of an atom coupled with single-mode cavity field exactly, and compared the results with that of the Jaynes--Cummings (J-C) model. The results show that for resonant case, there is no Rabi oscillation for an atom. For small detuning and weak coupling case, the probability for the atom in excited state oscillates against time with different frequencies and amplitudes from that of the J-C model. It exhibits that the counter-rotating wave interaction could significantly effect the dynamic behaviour of the atom, even under the condition in which the RWA is considered to be justified.

Concurrence evolution of two qubits coupled with one-mode cavity separately

Liu Wei-Ci,Wang Fa-Qiang,Liang Rui-Sheng,

中国物理 B , 2010,
Abstract: The concurrence evolution of two qubits coupled with one-mode cavity separately is investigated exactly without adopting the rotating-wave approximation. The results show that for the resonant case, the concurrence evolution behaviour of the system is similar to that of the Markovian case when the coupling strength is weak, while the concurrence vanishes in a finite time and might revive fractional initial entanglement before it permanently vanishes when the coupling strength is strong. And for the detuning case, the entanglement could periodically recover after complete disentanglement. These results are quite different from those of system subjected to Jaynes--Cummings model.

Journal of Chongqing Normal University , 2011,
Abstract: In the background of urban and reral balanced development, in order to promote the understanding for rural development in Chongqing , and this article evaluated its economic and social development. Based on the development status of Chongqing's urban and rural areas, we set the indicators system of evaluation for Chongqing rural economic and social development, and prove its reason through the factor analysis and gray relational analysis. Finally we get the composite score and ranking of each district. Taking cluster analysis to composite scores and correlation analysis with per capita investment in fixed assets, road density and the economic pattern,and also taking hierarchical display, we get three levels area of rural development status, and prove that it is correct to increase investment and build infrastructure and make a rational economic distribution. It also shows that , for every regional rural economic and social development states, an hour economic areas is better than the northeast of Chongqing ,and the northeast of Chongqing is better than the southest of Chongqing overall. Finally, we try to explore some overall measures for superior areas such as an hour economic area, Wanzhou district and poor areas , the northeast and the southeast of Chongqing and Tongnan county in the west edge.
